Arduino pins

Each motor needs three pins, two normal digital output pins for setting the direction, and one PWM pin that sets the speed.
I started with pins 6(PWM)/7/8 and 11(PWM)/12/13. Works well.
I added infrared control software IRRemote. The motor connected to 11/12/13 doesn't turn anymore.
Solution: Use pin 5 instead of 11. IRRemote seems to use pin 11 to implement timer interrupts; I don't quite understand the details.
